Hello, I'm curious, hence I ask you; Is there such a "recent college engineer", either software or hardware, or one that studied both, who would meet all of these requirements:
embedded Linux based data telecommunications system/ VoIP/SIP
satellite network application and
embedded software/ Firmware/embedded systems
automation scripting
Python
Java
Linux operating system/Linux Network expertise
Unix shell scripting
WEB GUI test automation
DO-178B experience
Satellite communication experience
Telecommunication experience/PBX switching systems

Any comments?
Do companies expect to find an "expert" engineer with all this knowledge?
thanks

Typing on mobile: some thoughts

I was thinking the other day about smartphones and how I often don't like to type on them. I'm just so used to typing on full-size keyboards, that typing on mobile is like swimming in molasses. And it's really a shame, because in so many other ways, my iPhone is incredibly convenient.

But then, I thought about how speech to text these days is pretty decent, and perhaps the best approach would be to just use Siri for dictation instead of trying to type. I've held off on such things, because I'm old enough (and had enough bad experiences with flaky computer dictation long ago) that psychologically, it feels really weird to talk to a computer.

But in this case, my computer is a phone.

And that means: I feel weird talking to a phone.

Which is kind of weird, don't you think?

What about you? Do you type on your smartphone a lot? Or do you use Siri/Cortana/Google for dictation? Does talking to your phone feel weird or is it totally normal for you?

Stacy: I'm curious... Why do you hate talk to text?
Not speaking for Stacy, but I too get frustrated with 'Siri' sometimes, especially so if I'm driving and try to initiate a hands free call to some of my contacts. I tend to drive with my windows fully down almost all year round so I guess the ambient noise probably doesn't help, but it can be incredibly frustrating when two out of three calls tend to work perfectly!

A typical example goes something like this..
1. Hey Siri, call Tom Smith, office..  "Calling, Tom Smith.. office"   Tick! - Successful call
2. Hey Siri, call Bob Jones, mobile.. "Calling Bob Jones.. mobile"  Tick! - Successful call
3. Hey Siri, call Jennifer Clayton, office..  "Calling John Mechanic, office.."  Huh?!?!

Might take two or three attempts before she finally gets it right and I've had to explain myself a few times when not paying much attention to Siri's answers (which most times I'm not) and the call goes through to someone I had no intention of calling.

One amusing time she wrongly called my dental surgery and I ended up making an appointment for a routine checkup during the call. Turned out I needed a filling so that call ended up costing me about $150.00!! lol..

I'm sure others must have also experienced this phenomenon as well? :)

One reason of not liking talk to text if you ever been on the end of the message that has not been read over before sending is really confusing and can cause some problems.

Second reason just listening to someone use talk to text is simply annoying to me. I don't want to hear the conversation you are having.

This is just my opinion.

I have a phone within my organization, while on DND, if called on the outside direct number, it rings while it's on DND.  Does anyone know how to program it to forward to voicemail and not ring through while the phone is on DND.

We have a MITEL System

I used this Note 5 for 2+ years with a great experience.  Great phone - large bright screen 5.7" 2560x1440 pixels, fast 4GB RAM and 32GB Storage, 16mp camera.   All good except.. battery life is terrible.  Time for an upgrade.  
Should I stick with Samsung and go with Note 8 or what would be other recommendations?  

Thanks in advance.

I just signed out of a Google Voice account on my Samsung Galaxy S8 phone.

I have logged in with another Google Voice account which is the one I want to have associated with my cell phone.

The problem is that when I make phone calls using my Samsung Galaxy S8 phone the caller ID for the most recent Google Voice account (510-xxx-xxxx) displays instead of the caller ID for the other Google voice account I have switched back to (415-xxx-xxxx).

I also remember that when I have set up Google Voice numbers in the past that these Google Voice numbers have given me the option to fully integrate Google Voice with my Sprint PCS phone (which is what I want to do now). However I am not given this option at this time.

What do I need to do to fix this issue so that the phone number associated with my 415 area code Google voice number will display whenever I make phone calls?

I own an Avaya ACS509 R7 BUSINESS PHONE SYSTEM NAMED PARTNER. One of the extensions,the main programming extension number 10 is not functioning 100%.There is an illuminated button that can be designated as DND (Do Not Disturb). The button does make a click in the receiver but does not turn on the DND feature nor does the led come on. I have tried several identical phones on that  line and none of them work. All of them work different extensions. So, I must assume it is the main controller board. I am an Electronic Technician and probably can repair it IF I could locate a complete schematic diagram along with pcb board layout pictorials and part numbers/values. I do NOT need the programming manual or user's manual. ONLY a technical repair manual. They must exist somewhere since there are several locations that will repair this motherboard. I would really appreciate it if any Expert could direct me to a pdf or similar for this unit. It is also referred to as an ACS-R7 unit. Anyone assisting me will be the recipient of 735 virtual Kudos!

NOTE: This is NOT a voip system. Just a regular 20 extension phone system.

 Watch the Recording: Learning MySQL 5.7

MySQL 5.7 has a lot of new features. If you've dabbled with an older version of MySQL, it is definitely worth learning.

I'm trying out a few different UK network sim cards.  For EE under the Enable 4G setting it offers, OFF, Voice & Data and Data only.

What has voice got to do with 4G because the other network sims dont mention Voice and data only data.

Hello everybody,
I am a junior telecom consultant and am working on a ToIP migration project.
My client has some specific needs to be satisfied in his new ToIP network and i need your help as soon as possible.
in fact i have 2 questions :
             * Can we chain 2 IP phones on the same PoE switch port knowing that the 2nd phone will be connected to an external power
                supply  ?
             * What are the potential risks or the disadvantages of chaining the PC behind the IP phone ?

It will be helpful also if you can share with me a document describing this topic.
Thanks in advance, i'll be grateful.

I am using a grandstream IP PBX UCM6202 and GoIP8 as a VOIP Gateway.
when i dial a number in this pattern +960 7788340 from PBX the call goes out to GoIP gsm gateway but from the GoIP outgoing call has a some unknown character due to space in front of digit 7. for this reason call is not dialed. if there is no space then there is no issue with the call going out. i am using an iphone numbers stored in contacts by defaults has some spaces. is there a way to remove the space when dialled out from GoIP gateway
below is a link to GoIP

My company wants to compare pricing on hiring a full time switchboard operator versus outsourcing to an answering service.  We have one published number for the company even though all departments have a DID line.  The company is against automated attendant so the current choices are 24/7 answering service versus hiring an operator.  The idea is that the company main number would be forwarded to the answering service who would take the call and answer as "companyname."  They would then transfer the call to a DID number at our company to complete the call.  Obviously, the answering service would have a directory of DID numbers to forward to.

I am looking for some answering services that people have tried and have been happy with.  I just want to get an idea on pricing since we'd be comparing it to hiring a full time employee.

Please provide me with a URL address of the Sprint PCS add a phone program.

I know several users who all currently have a single Sprint PCS cell phone and are interested in finding the details of how they can add a second phone to their Spring PCS account using the current Sprint PCS promotion that we have heard is going on until the end of June of 2017.

Need to run direct burial CAT5E with telephone signal lines and intend to terminate with RJ11 plugs.
I find that the wire insulation diameter is a bit large to assemble the cable end into the plug.  
I suppose that I could terminate the CAT5E cable with a modular jack and then use a telephone cord (RJ11-RJ-11) from there.
Yet, the same issue isn't anticipated on RJ45 plugs.
Is there a wire diameter (including insulation) specification for RJ11 that's smaller than for RJ45?

Portable, direct connect server access
Portable, direct connect server access

The ATEN CV211 connects a laptop directly to any server allowing you instant access to perform data maintenance and local operations, for quick troubleshooting, updating, service and repair.

Does anyone know why the switch slows down so much that the VOIP starts to have Jitter and after a reboot it works fine for a week again. The switch runs the PC's through the Phones. There are no VLAN's programmed at the moment. The switch is stock standard. Are there any settings I can change?

Hello all,

I have some Win 2012 3cx v15 phone systems and was having trouble with apple push notifications for calls to remote devices.  I've determined it to be a TLS issue.  I had used IIS Crypto to remove the less secure SSL 3.0, TLS 1.0 and 1.1, leaving just TLS 1.2 and more secure ciphers.  This breaks apple push notifications from the 3cx server/software.  I put back TLS 1.1, no luck.  Put back TLS 1.0, now push notifications work.  I find it odd that I should still need 1.0 enabled on the server.  

Is apple push still using that protocol and not 1.1 or 1.2, or might there be something else going on here.

I'm by no means familiar with protocols/ciphers, just determined what fixes the problem.
